摘要：
The variation of the I-1/I-3 ratio of the fluorescence of pyrene in polystyrene-based quaternary ammonium salt (PA) and sodium carboxymethylamylose (NaCMA) aqueous solutions was measured as a function of sodium perfluorooctanoate (SPFO) concentration. Association of the anionic fluorocarbon surfactant with cationic polyelectrolyte (PA) to form mixed micelles occurred at the surfactant concentrations far below its normal critical concentration, while no interaction between SPFO and anionic polyelectrolyte (NaCMA) was detected. The driving force for the formation of mixed micelles of SPFO and PA is electrostatic interactions.
